You could run this command to check your NTFS partitions:
chkntfs /d

It must run on all local drives, including removable and fat32. Also, the
chkntfs /d run on volumes with dirty bit set, and errors could exist even
when this bit is not set.

@echo off

if exist %%x:\ echo.y|chkdsk %%x: /f)

Have you changed your requirements? You initially wanted something that runs
chkdsk on the next restart. The current solution will run chkdsk immediately
on all non-locked drives.

In a one-liner! But another question arises: since seems that the echo.y is
valid on english systems, how always answer 'yes' on any OS language?

Thank you charles.

this could be avoided by unmapping drives first, i.e.:

This has nothing to do with the subject but your PC clock appears to be two
hours fast, or else your time zone is set incorrectly.

Can't tell - this depends entirely on your requirements.

What would be the best/fastest option and why?

1) Set dirty bit on on all 'fsutil fsinfo drives', preceded by chkntfs /d
and chkntfs /t:0 (leaving all the work to the restart)
2) Chkdsk /f on all unlocked volumes immediately, leaving the only locked
volumes to the next restart

Pegasus, just to give a little more detail. This script code will be at the
end of another, and would run or not according to a CHOICE %errorlevel%
right before. The whole script is used at a computer service shop and to
regular maintenance of workstations, that can vary greatly in languages (so
the issue with echoing 'y' as answer) and drive letters.

It seems there is no need for you to defer the chkdsk command until the next
reboot.

To avoid having to pipe "Y" into the chkdsk command you could use my
registry preset approach. Alternatively you can probably use this batch file
to find the "Y" equivalent in different language installations. I haven't
tested it on non-English machines.
@echo off
for /F "delims=" %%a in ('copy /? ^| find /i "copycmd"') do set line=%%a
call :Sub %line%
set Yes=%Yes:~1,1%
echo Switch=%Yes%
goto :eof

:Sub
set Yes=%1
if "%Yes%"=="" goto :eof
if %Yes:~0,1%==/ goto :eof
shift
goto :sub

Thank you for the 'yes' approach. The following is a code to set dirty bit
on all drives listed by fsutil, could be smaller but works fine. Method
fails to check fat32 volumes, so the chkdsk script from charles seems
better.

@ECHO OFF

CHKNTFS /D
CHKNTFS /T:0

SETLOCAL ENABLEDELAYEDEXPANSION
SET Drives=

FOR /F "skip=1 tokens=1,2 delims=\ " %%A IN ('FSUTIL FSINFO DRIVES ^| MORE
/E /T0') DO (
IF "%%B"=="" (
SET Drives=!Drives! %%A
) ELSE (
SET Drives=%%B
)
)

FOR %%A in (%Drives%) DO FSUTIL DIRTY SET %%A

Thanks for pointing this out. I have actually moved two timezones east for a
couple of months, and somehow neglected this little detail. I'll try to
remember to fix that a bit later.
